Price of good or service
An increase in income causes consumers to demand more of a good, all other variables are constant
Normal Good
Other goods and services consumed less if there is an increase in income.
Inferior Goods
An increase in income can cause the amount of commodities that consumers purchase to either increase or decrease.
Consumers’ income

Substitutes
Goods that are used together.
Complements
If there are two substitutes, an increase in the price of one good will increase the demand for the other good.
Prices of related goods and services
If the price of a good increases, the demand for the other good decreases.
Prices of related goods and services
Demand will increases as consumers see it as having higher quality, more fashionable, healthier, or more desirable in any way.
Consumer’s preferences
Demand will decrease when consumers perceive falling quality, displeasing appearance, or unhealthiness.
Consumer’s preferences

Expected price of the product in future periods
If consumers expect the price to decline for a future period, demand for the current period will fall.
Expected price of the product in future periods
Increase in the number of consumers will increase the demand.
Number of consumers in the market

States that all things are equal, an increase in price results in an increase in quantity supplied.
Law of Supply
The higher the price of the product, the greater the quantity produced. All other things are equal.
The price of the good
The lower the price of the product, the smaller the quantity produced. All other things are equal.
The price of the good
Increase in the price of one or more of the inputs will increase the cost of production. If the cost rises, it becomes less profitable and will produce smaller quantity.
The prices of inputs used to produce the good
An increase in the good X relative to good Y causes an increase in production of good X and decrease production of good Y.
